Instructionsheet - D4B-2A71N

Omron D4B Series Limit Switch, IP67 Ingress Protection, 1 NO/1 NC Contact Configuration - D4B-2A71N

This limit switch is a compact mechanical device that detects position changes and provides a swift electrical response in industrial control systems. It is built for installation where a robust, snap‑action contact is required and is suited to environments that demand ingress protection and wide temperature tolerance.

Features and Benefits:

• Snap‑action contacts deliver clear switching at 400V switching voltage
• Metal housing offers robust protection for electrical components
• Rated ingress protection IP67 prevents dust and water ingress
• Operating force of 9.41 N ensures consistent actuation feel
• Mechanical endurance of 10,000,000 cycles supports long service intervals
• Screw terminals enable secure field wiring connections

Applications

• Used with conveyor systems requiring precise end‑of‑travel detection
• Suitable for actuator position sensing in automated machinery
• Ideal for outdoor enclosures exposed to moisture and dust
• Can be used for safety interlocks on heavy plant equipment
• Used for limit detection where multi‑directional mounting is necessary

What terminal connection method does it use for wiring?

It employs screw‑type terminals that allow direct conductor clamping for reliable electrical contact.

Which contact arrangements are available and how do they operate?

The unit provides one normally open and one normally closed contact using a snap‑action mechanism for rapid, repeatable switching.

How is conduit connection achieved on‑site?

A G1/2 conduit entry is provided to accept standard conduit fittings for protected cable routing.

What environmental temperature range can it withstand?

The device operates from -40 °C up to 80 °C, supporting cold‑start and high‑temperature applications.
